What is the Boiler Upgrade Scheme (BUS)?

The Boiler Upgrade Scheme is a UK government initiative designed to enhance energy efficiency and lower carbon emissions by encouraging homeowners and businesses to replace outdated, inefficient boilers with advanced energy-efficient systems. This programme is part of a larger strategy to combat climate change and reduce the environmental footprint of heating, a major contributor to greenhouse gas emissions.

Recently, the UK government raised the grant for air source heat pump installations from £5,000 to £7,500. However, eligibility criteria apply:

- You must own the property where the installation will occur.
- The installation should have been completed or planned for on or after 1 April 2022.
- The new system must replace an existing fossil fuel heating system (gas, oil, or electric).
- Your property must hold a valid Energy Performance Certificate (EPC) with no pending recommendations for loft or cavity wall insulation.

For those uncertain about eligibility, completing our form allows us to arrange assessments with an MCS-certified installer who can guide you through your options.

*Please note: The grant is available to homeowners in England and Wales only. Homeowners in Scotland may qualify for an interest-free loan or grant to enhance energy efficiency, and Northern Ireland offers grants for boiler replacement.*

How Do Air Source Heat Pumps Function?

Air source heat pumps operate through a process somewhat akin to solar technology. Inside the air-to-water heat pump is a chemical liquid that evaporates when absorbing heat from the surrounding air. This evaporated substance is drawn into a pump, which moves it into a smaller chamber. As the chemical nears its boiling point, the resulting steam is directed toward a condenser, where heat is released into your home’s heating system.

These pumps provide the necessary warmth for various heating systems, including radiators, underfloor heating, and warm air convection units. There are two primary types of air source heat pumps:

- Systems with a component positioned outside the immediate boundary of the home.
- Installations that coexist with an existing ground source heat pump on-site.

Maintaining Your Air Source Heat Pump

Air source heat pumps are generally low-maintenance systems. During particularly cold weather, you might notice some ice build-up on the pump; however, in most cases, the pump will defrost itself automatically. Occasionally, you may need to assist by switching off the unit temporarily to allow for manual defrosting.

To provide extra protection from harsh British weather, some homeowners opt to place a small shelter over the outdoor component of the heat pump. This simple measure can help safeguard the unit from potential weather-related issues.

How Much Does an Air Source Heat Pump Cost?

The cost of air source heat pumps, including supply and installation, typically ranges from £6,000 to £10,000. Last year, over 22,000 British homeowners opted for heat pump installations, and demand continues to grow annually.

Through the Boiler Upgrade Scheme (BUS), a government initiative aimed at promoting renewable heating, you can receive a £5,000 grant to offset the cost and installation of an air source heat pump.
